I have been off of chewing/dipping for three months now, and it is just now becoming somewhat normal.
Some may wonder how I did it. It was with encouragement from the VA hospital. They recommended Bupropion which frequently is used for depression. I said that I would not take anything that might contaminate my medical records. I was assured that its alternate use was to curb smoking and that my records would be so noted. Actually is is stated "To curb tobacco usage." It has worked so far, and I am no longer taking it. I swear that it did nothing and that it was my shear will power that made me stop. Who knows, I never quit before after numerous attempts.
